Hi Lorenzo,
<div><br>
</div>
<div>Just to clarify, by the renormalized ones you are referring to the EPI-renormalized electronic band structure (which is what I am after)? </div>
<div><br>
</div>
<div>Thanks,</div>

<pre wrap="" class="moz-quote-pre">I am attempting to compare PbTe band structure at 0K and 300K using the postahc.x code. The code does print the renormalized self-energies (Example 19 in the PHONON package) but does it store the EPI-renormalized band energies anywhere? </pre>
</blockquote>
<p>I'm not familiar with this code, but it should be enough to add the imaginary part of the self-energy (which is usually negative) to the unperturbed phonon frequency to get the renormalized one.</p>
